No reason to spend $$$ on a wear item. This chain one of the best bang for the buck items out there. Now you can afford to replace that chain before it starts to wear out your drivetrain
For the last year this has been the pack that i have used the most. With a little effort I can fit a 60m 10.5mm rope, harness and shoes in it. The side compartments are plenty big enough to hold one 1litler of water each.
I've used this pack on 3 different walls now (the nose, moonlight and Washington column). It doubles fairly nicely as a rope bucket. Great as a day pack to put water, food, extra shoes and a jacket in. And it fit our entire rack for the nose in it for the decent. I wouldn't haul with it though. I wore right through the brain of the pack after dragging it up one pitch.
The tarp is plenty big enough to put a rope on it. granted bigger ones are nicer for craggin but it was nice to have a tarp to use on a multi pitch climb and be able to stow it away in my pack and not have to leave anything at the bottom.
